Now I have played a lot of Halo, it’s primarily all I play, and I can’t believe I can’t remember ever not being able to snipe flood. Has it always been like that?
Which Halo? In Halo: CE, yes. It has always been like that. The shots just go right through them. But in Halo 2 it can be done if you know where the head shot hit box is. I’ve never tried it in Halo 3.
Yes, in CE! Dietz even made a note of it in The Flood 
I believe it was in the chapter adaptation of the level “Keyes.”
Ok from Halo 2 that is what I am remembering. Trying to grind out the last two par scores I need on Halo CE, The Keys and the Maw. I was trying to snipe a few flood where you get the sniper rifle on the keys to no avail.

yeah, save that ammo for covies. The flood’s biomass is said to be so spongy that the bullets go through them with no real signs of damage (retconned by 2 and 3 however.)
